AI 中文摘要
本研究提出一种用于大面积生物医学应用的便携式平面氩基等离子体射流,重点关注均匀放电、稳定性和安全性。该装置配有可互换的后部和侧面进气适配器,适配器带有限流板和通道以均衡气流;电极封装在低温共烧陶瓷(LTCC)中,以减少重复运行期间的降解和电弧。对多种通道构型进行了流动模拟,以确保层流分布和均匀等离子体产生。以kinPen MED为参考标准评估装置性能和安全性,系统测量了电气特性、光发射、放电均匀性、温度、气体速度、臭氧产生量、紫外线辐照度和漏电流。等离子体在初始预热后呈现稳定的电压、电流和功率;温度在数分钟内稳定,其中后部进气构型因出口气体速度更高而表现出更低的工作温度。臭氧水平保持在既定安全限值以下,紫外线暴露限制了允许的处理时间,漏电流随距离增加而降低,在短间距时接近安全阈值。这些结果表明,所提出的平面等离子体射流可提供稳定、均匀的等离子体输送,同时满足关键安全要求,支持其在临床和生物医学领域的应用潜力。
英文摘要
This study presents a portable planar argon-based plasma jet designed for large-area biomedical applications, with an emphasis on uniform discharge, stability, and safety. The device incorporates interchangeable rear and side inlet gas adapters with restriction plates and channels to equalize gas flow, while electrodes are encapsulated in low-temperature co-fired ceramics to reduce degradation and arcing during repeated operation. Flow simulations were conducted for multiple channel configurations to ensure laminar gas distribution and uniform plasma generation. Device performance and safety were evaluated using the kinPen MED as a reference standard. Electrical characteristics, optical emission, discharge uniformity, temperature, gas velocity, ozone generation, UV irradiance, and leakage current were systematically measured. The plasma exhibited stable voltage, current, and power after an initial warm-up period. Temperatures stabilized within minutes, with the rear-inlet configuration demonstrating lower operating temperatures due to higher outlet gas velocity. Ozone levels remained below established safety limits, while UV exposure constrained allowable treatment times. Leakage current decreased with increasing distance and approached safety thresholds at short separations. These results demonstrate that the proposed planar plasma jet provides stable, uniform plasma delivery while meeting key safety requirements, supporting its potential for clinical and biomedical use.
